#define LED pin
led=[12,13,14,15,16,17,18,19]
leds = [Pin(led[i], Pin.OUT) for i in range(0,8)]What I don't understand is why there is a statement on the left side of for. I have never seen this form ...
Problem description:In Proteus simulation, a network label error occursSolution:Modify the network label. For example, if the error message shows that the network label is D5, change the label D5 to P...
I am using the MSP430G2 LaunchPad to run an example program on IAR to flash an LED. Everything works fine when debugging, but after exiting debugging, the flashing becomes extremely slow! Pressing RST...
5V comes from TTL level, 5 is True, 0 is False, and then the PN node with lower voltage drop was used to derive the 3.3 level.12V and 24V come from car batteries. In the early years, passenger cars ha...
